Borla XR-1 Multi-Core 3in Ctr-Ctr Oval 16in x 4.25in x 7.88in Rotary Engine Equipped Racing Muffler

If you're building a high-horsepower rotary engine or any application where space is tight, this Borla XR-1 Multi-Core racing muffler is a solid choice. It's designed to flow as well as a straight pipe, meaning it won't choke your engine's performance, especially when you're pushing serious power.

This muffler uses Borla's patented Multicore technology, which helps manage sound without sacrificing flow. It's constructed from T-304 stainless steel, so you don't have to worry about rust, and the 100% welded build means it's strong enough for demanding use. The compact oval shape, measuring 16 inches long by 4.25 by 7.88 inches, makes it a good fit for vehicles with limited undercar space. Plus, its reversible design gives you flexibility during installation.

This muffler is built in the USA and uses high-temperature acoustic material to control sound. While it's specifically mentioned for rotary engines, its design makes it suitable for other high-horsepower applications where a compact, free-flowing muffler is needed.
